Someday submit a competitive application which includes high GPAs in all courses and in premed courses, do well on MCAT, participate in ECs that show you have qualities med schools expect to see (eg leadership, compassion, altruism, show you have some idea what you’re getting into, etc), get strong LoRs, write a compelling personal statement that explains why you want to be a MD, do well on interview, apply broadly, and as 60% of those that actually apply to med school fail to get even one acceptance, you can keep fingers crossed and/or pray after you submit your application.
However, before you submit your application, you should consider colleges where you think you’ll fit in as if you’re happy you more likely to do well. There will be many colleges that can do this. Why bio? You can be a history, Spanish major, whatever major etc. Med schools simply do not care what you major in. Pick a major that interests you as you’re more likely to do well GPA wise if you’re happy. Most premeds pick bio, maybe out of interest, but also because one satisfies major and most premed reqs at same time whereas as a history major, it may be difficult to schedule in premed reqs. But as the vast majority of premeds who show up on day one change their minds and never apply to med school, you should have a Plan B. The job market is not good for bio majors, again why bio? I don’t need an answer, just meant to be food for thought. As med school is crazy expensive and is typically paid for by loans, consider colleges where you can graduate with as little debt as possible. And as you’re looking at at least 4 years of college, 4 years of med school, 3-5 years residency, more years if you pursue fellowship training, are you prepared to say bye bye to your 20s and a chunk of your 30s. Good luck.
